MARION G. SLAWSON, 0F GIRARD, KANSAS.

GRAIN-SHOCKER.

To all whom t may concern:

Be it known that I, MARION G. SLAwsoN, a citizen of the United States of America, residing at Girard, in the county of Crawford and State of Kansas, have inventedl certain new and useful Improvements in Grain-Shockers, of which the following is a specification.

This invention relates to grain shockers' of a. type adapted to be secured to and to travel with a grain binder of the usual construction, said shocker receiving the bound bundles of grain from the binder, retaining saidbundles until the desired number have been collected and then vdepositing said bundles in the form of a shock upon the ground. Broadly speaking these objects are attained by a structure comprising a frame in-which a table is slidably mounted, together with means for conducting the bundles of grain to said table, shock forming arms onngers for retaining the bundles in an upright position upon said table, means for causing the table to move into the frame and from beneath said bundles at the will of the driver, fingers for vsupporting the bundles when the table is withdrawn from beneath them, and automatic means for dropping said ingers and opening the shock forming arms when the table reaches its limit of movement toward the front of the machine.

The shocker herein shown and described is somewhat similar in construction to that shown in my prior patent #985,7 50, issued on February 28, 1911, but it comprises certain improvements and additions thereto that are of the utmost importance and which VI have found to be of a `high degreev of utility.

These improvements comprise, among other things, alternately acting sets of packers which have a longitudinal reciprocation imparted vto them, said packers being disposed adjacent the. entrance to the shock forming arms, and acting to crowd the bundies into the shocker by getting in front of the bundles and pushing them rearwardly. The packers upon the opposite sides of the machine alternate in this packing action vand thereby create a tight and Well formed shock. I also employ a binding apparatus in conjunction with the shocker, this bind- Specicaton of Letters Patent. Patented Sept. 12, 1916. Application led February 27, 1913. Serial Iio. 751,075. g

ing apparatus serving vto tie a string around the topof the shock. I Furthermore, in the present structure, 'I have arranged a trip the chains which carry the bundles rearwardly from their driving elements, so that at vthis time, the packers. and chains arev stopped ramd no bundles/will .be carried .through into the shock forming arms when said arms are in open position'when setting out the completed shock.- The movement of the table to its shock supporting position, serves to actuate this clutch to again establish connection between the 4chains and packers and their driving elements, so that these members are set in operation to carry the bundles rearwardly and to compress the bundles into the shock.

Means are provided for preventing the bundles from falling over-until the chains properly engage them and a butter has been provided to carry the butts of the bundles down into engagement with the bottom chains,`these bottom chains being slightly divergent at their forward ends to form a throat to permit of the ready engagement of the butts by said chains.

It is a further object ofthis invention to provide a bottom board for the passageway for the bundles duringA theirr rearward travel, together with means 'for varying and adjusting the inclination of said board so that it may be raised or lowered as needed Vto handle the different lengths of straw. Means are provided for preventing the bundles from the binder from being .discharged over the top of the shocker.

Improved mechanism has been provided I am familiar, are

so constructed that Ithey All of the shockers now made, with which being forced toward each other by the 'springs and by reason of their being spring actuated and hinged, separating to permit the passage of the bundles of grain and then moving toward each other, under the "nfluence of said springs, to get in front o the bundles to aid in holding the bundles firinly into the shock.

Further objects and advantages of the invention will be set forth in the detailed description which now follows:

Like numerals designate corresponding parts in all of the figures of the drawings. In the drawings, designates a. portion of a grain binder and 6 designatesthe rectangular frame of the shocker. This frame is connected to the grain binder by an intermediate fr'ame '7. The frame 7 carries an arm 8 that is actuated by a spring 9 to force .an idler roll 10 into engagement with a .incense sprocket chain 11 te thereby prevent yundesirable looseness of .said

chain. j .This

sprocket'chain passes over a sprocket wheel 12 upon a shaft 13; Shaft 13 is one of the shafts of the grain binder and motion is imparted from this shaft to the longitudinal shaft 14: of the shocker through the medium of a sprocket wheel 15.

. As has hereinbefore been set forth, the invention comprises a slidably mounted table which, during the time the shock is formed,

stands beneath the shock forming arms.`

After the shock is formed and is ready to be discharged, mechanism (hereinafter deit is slidably mounted to travel in the frame 6. .,Longitudinal motion is imparted to the table bysprocket chains 17, to the under flights of"\vhich the forward end of the table is attached. rlhese sprocket chains pass over sprocket wheels 18 and 19, the latter of which are mounted upon a transverse shaft 20. Shaft Q0 carries a bevel gear wheel 21 whiclf'is-in mesh with bevel gear wheels 2Q and These latter gear wheels are loose upon shaft 1-1."

A clutch 21 is splined upon shaft Mend is adapted to be thrown into engagement withAM gear wheel or 23 through the medium of a lever 25. This lever is pivoted at 26 upon frame 6 and its free end engages clutch 24. A latch 27 is'pivoted upon a post 28 and is normally held into engagement with lever 25 by a spring 29.

The driver of the grain binder may release this latch by pulling upon a cord or cable 30 which passes over an idler pulley 31 (see Fig. 3). Y

A slotted link 32 engages a pin 33 carried by lever 25, vsaid slot providing a lost motion connection between said link and said pin. A roller 34 is .carried by the lower end of this pin and this roller is controlled by a spring actuated Cam 35. This cam is mounted upon the end of a rod 36, said rod being slidably mounted in -eyelets 37 A spring 38 bears between one of these eyelets and a collar 39 carried'by rod 36, and normally tends to force the cam toward the roller.

r1 he operation of this portion of the structure is as follows: l/Vith the parts in the position shown in Figs. 1 and 3, the trip lever 27 is in engagement with lever 25 and the 'cam 35 is, under the action of spring 38,

gagei'nent with gear wheel Q3, which action will start shaft 2O and cause the sprocket chains 17 to draw'the table into theframe and from beneath the shock. Tt is'apparent, therefore, that when the driver of the grain binder trips lever 27, such action will take place. That is, the table will be caused to travel into the frame. l/Vhen the table reaches its limit of movement into the frame, however', it acts through mechanism, hereinafter described, to impart a partial rotation to a transverse shaft 40. This shaft carries.

said cam so that after this roller once passesl the nose of the cam, the cam will act to hold the clutch intol engagement with gear wheel 22. Then the table reaches its limit of outward movement, it acts through mechanism,

vhereinafter described, to impart a reverse movement to transverse shaft 40 to draw the link 32 toward the right. This again pulls lever 25 toward the right until the roller 34 again passes the nose of the cam. The action f v.of the cam would then cause the lever 25 to move over to bring the clutch into enga-ge;-

ment with the gear` wheelQMi-flvit'were not for tli'emfacttha't'" the trip 27 engages the lever and prevents such complete movement.:

In other words, the movement continues until the clutch reaches a vneutral position, whereupon the trip engages it and prevents it from 'moving farther until the driver again releases said trip. T0 hold the transverse shaft 40 in either of its positions, a rod 42 is slidably mounted in a block .43 and is normally forced outward by a spring 44 which bears between said block and nuts 45 threaded upon said rod, and by which nuts the tension of the spring may be adjusted.

This rod has a bifurcated outer end 46 which is pivoted to a crank 47 fast'upon shaft 40. Consequently when this crank moves beyond the center in either direction, it is held in the position to which'it moves by the action of said spring.

It will be understood that ...the shocker travels bodily with the grain binder and for this purpose it is mounted upon ground wheels 48 and when the bundles are delivered from the grain binder to 'the shocker, they fall into a passageway 49, the bottom of which is formed by a. board 50 and the'sides of which are formed by frame members 51 and sheet metal coverings therefor indicated at 52.

The elements c rearwardly to 'the sho y way 49. l 1

To insure the butt end of the bundle be prise .lower sprocket chains sprocket chains 52'32", 'these carrying prongs to pci. cient engagement withthe bunnies.v

To prevent the bundles from being discharged entirely over the outer frame member 51, I arrange a .pair of upstanding arms 51a in such position as to intercept the bundles and to direct them into the passageing carried down into engagement with the l lower sprocket chains, I provide an endless canvas butter 55 to which motion is imparted by bevel gearing 56 from one of the forward vertical shafts 57 upon which the forward sprocket wheels 58 for the lower sprocket chains are mounted.l

To prevent the top of the bundle from falling over before it is properly engaged by the upper sprocket cha-ins, spring fingers 59 are carried by the vertical shafts 60 upon which the sprocket wheels 61 for the forward ends'of the upper sprocket chains are mounted. These spring fingers project into the path of the bundle but they do not move with the shafts 60. They are merely sup ported thereby, and these fingers yield to permit the bundle to pass, after which they spring back into position.

To form a throattand to thereby permitof the more ready engagement of the bundles by the' lower sprocket chains, these sprocket "ffir chains are arranged slightly divergent at their front ends as is clearly illustrated in Fig. 1. The necessary movement is imparted to the sprocket chains through the rear vertical shafts 62, these shafts in turn' being driven by the bevel gears 63 from transverse shaft 64 and-this shaft 64 being in turn driven through bevel gears 65, 65', from the longitudinal shaft 14.

'A clutch 66 which will be more specifically described hereinafter, is larranged when the table starts forward, to disconnect gear 65 from shaft'14 so that during .the movement of the table, the chains and the packers 67', hereinafter described. will be stopped. These packers are driven from 'cranks 67 formed in shafts 62 and the rear ends of the packers are pivoted to links 68 which links in turn are pivoted to the frame members 51. Therefore, when the shafts 62 are rotated, an alternate thrusting movement 1s imparted to these packers to crowd the` I formed in them to permit the packers to act through said shields. Normally, these `shields are held in the position illustrated in Fig. 1, by springs 72 whichbear between the rear portions of said shields and the side frame members 51. As the bundles are carried along by the prongs 54, the shields yield inwardly to permit the bundles to pass therebetween and after each bundle passes, the shields move outwardly to cause their angular ends 7 3 to engage behind the bundles' and aid in forming and maintaining a tight shock.

. aid in maintaining the shock when the shock is seated upon the the transverse shaft is Vertical shafts 74 carry the arms 75. These shafts carry cranks 76 that are connected by links 77 with an operating rod 78. This operating rod is connected by a link 79 with a crank 80 of transverse shaft 40 and these connections act when the table reaches its forward limit of movement and given a partial rotation, to move the operating rod rearwardly or to the right in Fig. 1 and to thereby swing the shock forming arms open to release the shock.

I have found that it is highlyy desirable to tie a string around the top of the shock to formation of the ground. To that end, I have connected with shaft 14 through the medium of spur gears 81 and 82, a shaft 83 which drives through a bevel pinion 84 a bevel gear wheel 85 that is fast upon a binder head shaft 86. Upon the upper end of this shaft 86 is a bevel gear wheel 87 which meshes pinion 88 that drives a knotter, indicated at 89. The detail construction of this knotter has not been shown for the reason that it is of a type well known in the art and I deem it sufficient for the purposes of the present invention to merely indicate the position of the same and to show a driving means extended thereto from the remainder of the mechanism. A needle 90 acts in conjunction with the knotter in the usual and well known manner, this needle being mounted upon the upper end of a needle shaft 91V and being operated through a crank 92 and link 93, said link being pivotally connected at 94 to the underside of the gear wheel 85, so that as'this gear wheel rotates, the necessary swinging movement is irnparted to the needle 90.

Disposed within the length of the shaft 83 is a clutch 95 which, through means hereinafter described, is released to set the knotter or binding mechanism in motion when the table starts forward, said binding mechanism being automatically stopped after the operation of tying the string around the top of the shock has been performed. The means for accomplishing this will be hereinafter described.

The transverse shaft 40 carries cranks 96 and 97 and the free ends of thesel cranks carry pins 98. The cranks 96 and 97 are connected by rods 99 with levers 100. These levers are secured to pivots 101 and these pivots in turn carry arms 102 that are conshock forming with a bevel.

nected by links 103 with arms 104, the latter being pivoted at 105 to the frame 6.

Depending from the free ends of arms 104 are the side members of a U-shaped yoke 106, the body portion of which extends transversely beneath the fingers 107 Said fingers being pivoted at 108 to a bracket 109. The operation of this part of the .structure is as follows: When a partial rotation is imparted to the transverse shaft 40 to pull forwardly upon rods 99, the arms 100 and 102 are pulled forwardly to cause link 103 to swing arm 104 upon its pivot 105 to thereby lower the yoke 106 and to permit the fingers 107 to drop to the ground. It will'be noted that by virtue of this construction, the yoke is given a direct downward movement and the fingers -107 are so inclined upwardly that When they strike the ground, they set the shock squarely upon its butt in the stubble. When the shaft 40 is moved in the opposite direction, it is apparent that these fingers will be raised through the same connections.

Mounted upon the table and bodily movably therewith (see Figs. 1 and 12), are trip mechanisms comprising body brackets 110 having secured thereto keepers 111 and 112. Levers 113 and 114 are pivoted at 115 and 116 to body brackets 110 and the free ends of these levers are forked at 117 and 118 for engagement respectively with pins 98 of cranks 96 and 97 Aand pins 119 of arms 100. Therefore, when the table reaches its rearmost limit of movement, lthe forked ends 118 of levers 114 will act against pins 119 to raise the yoke 106' and fingers 107, and when the table reaches its forward limit of movement, the vforked ends 117 of levers 113 will act against the pins 98 to draw upon rods 99 and through `the connections described, lower the yoke. The table also carries a stop member 120 which actuates clutch 66 asv hereinbefore set forth, to stop the packers and the chains during .the time the table'is traveling forward and returning to'shock forming position. rlhis actuation of the clutch 66 is accomplished as follows: The movable member of the clutch 121 is engaged by a yoke 122 that is pivoted at 123 to a frame member 124. This yoke carries upon its underside a dog 125 that is pivoted at 126 to the yoke. A spring 127 has one' end attached to the dog and the other end attached to the yoke.` When the stop 120 strikes this dog, the clutch is shifted to disengage the movable member 121 thereof from the fixed member 121 thereof. This movement of the yoke changes the angle at which the stop 120 engages the dog and permits the dog to move over the center to such position that the action may be repeated but in the reverse direction, when the table moves outwardly again and it is deand .the portion 95?L A normally sired to again bring the packers and chains into operation.

The board 50 which forms the bottom of the passageway for the grain is adapted to have its inclination adjusted to thereby accommodate the varying lengths of grain by a crank 128, the central portion 128 of which bears against the underside of the board and the portions 128il of which are journaled in the frame (see Fig. 16). A hand lever 129 has a catch 130 which engages an arcuate rack 131 to adjust the inclination of the board.

The upper face of the gear wheel 85 (see Fig. 11) carries an egg-shaped cam groove 132 in which a roller 133 travels. This roller is carried by a rod 131 which has lost motion engagement with a rod 135 through the medium of ears 136 through which rod 135 passes. A spring 137 bears between one of the ears 136 and a p in 138 carried by the rod 135. The opposite end of the rod 135 (see Fig. 6) is connected to a latch 139 that is pivoted at 110 to a collar 141 that 1s loose upon shaft 83.

The clutch 95 comprises the two parts 95a and 95b and itis to be understood that the shaft 83' is divided by this clutch. That is, thetwo portions of the shaft separated by the'clutch only rotate in unison when the clutchis in operation. To this end the portion 95b is internally provided with teeth 95C is provided with a pivoted lever 95g" having a nose adapted to engage said teeth and when this noseis in en# Vgagement with the teeth, the Itwo parts of the clutch rotate in unison. A spring 95d tends to move this nose into en-l gagement with the teeth 95C. jVVhen the table moves toward the front of the frame, the stop 120 contacts with a lever 142 (see F ig. G) that is pivoted at 143 in such manner that it willyield when the table is passing rear wardly, but will act, when the table'is passing forwardly, to move the nose 139a oflatch 139 from the path of movement of the lever.` 95e. Thereupon the spring 95d acts to'bring the nose of lever 95e into engagement with teeth 95c and the two parts of they clutch and the two parts of the shaft 83 are caused to rotate in unison. rThis rotation continues until gear wheel 85 has made a complete."

revolution. In other words, as soon as rotation starts, the roller 133 is drawn upon by cam 132 to hold the latch out of action ,until the gear wheel 85 and the cam make a complete revolution, at the end of which revolution, the roller is again moved forwardly to cause the rearmost'ear 136 to act through the spring upon the rod 135 to again interpose latch 139 in the path 'of movement of lever` ,958, so that when this lever contacts with the nose 139a of the latch, the nose of said lever 95e is moved out of engagementwith teeth 95c and the gear wheel 85 ceases to charged from the binder -sageway .and are engaged by the prongs binding mechanism revolve. ln other words, this action takes place after a complete operation of the binding mechanism and the needle.

It is believed that the operation of the device will be apparent from the foregoing descriptiombut in order that said operation may be perfectly clear, it may be briefly stated in addition, that the bundles disfall into the pasupon the chains. The butter, 55 acts to carry the butts of these bundles down into the throat formed by thediverging of the lower chains at their front ends.

Carried rearwardly by the chains, past the yielding shield 69, these bundles are forced by the packers tightly into the shock forming arms. After a sufficient number of bundles has been collected, the driver of the grain `binder pulls upon the cord or cable to release the trip 27. il u Through the connections described, the table travels into the frame and from beneath the bundles, leaving these bundles resting upon fingers 107. During thisinward travel, stop 120 acts to trip the clutches 65 and 95 to stop the packers and chains and to set in operation the for tying a string around the top of the shock. At the completion of the inward movement of the table, the stop mechanisms carried thereby impart a partial rotation to shaft() to act upon rods 99 to lower the yoke and drop the lingers 107 and simultaneously therewith through the connections 78, 79 and 80, the shock forming arms are swung open and the shock is thereby dropped squarely upon itsbutt, and left standing in an erect position uponl the ground.

y While the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the lprecise construction set forth, but includes within its' purview such changes as may be .made within therscope of the appended sition, packers for forcing the `bundles into i said shock formingarms, said packers lying and acting in a horizontal plane to engage the vertically disposed bundles, means for driving said conducting means and said packers,` means for opening the shoclrforming arms to discharge the'wmpleted shock therefrom, and automatic means for stopping the action of the driving means of the v nism for packing the bundles of grain into 'carried by said table the shock forming arms, and means carried by said table for throwing the packers and conveying mechanism out of action during the forward travel of said table.
